# std::filesystem::path::parent_path

From cppreference.com
< cpp‎ | filesystem‎ | path

path parent_path() const; |  | (since C++17)

Returns the path to the parent directory.

If has_relative_path() returns false, the result is a copy of *this. Otherwise, the result is a path whose generic format pathname is the longest prefix of the generic format pathname of *this that produces one fewer element in its iteration.

### Parameters

(none)

### Return value

The path to the parent directory, or a copy of *this if not has_relative_path().

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <filesystem>
    #include <iostream>
    namespace fs = std::filesystem;

    int main()
    {
        for (fs::path p : {"/var/tmp/example.txt", "/", "/var/tmp/."})
            std::cout << "The parent path of " << p
                      << " is " << p.parent_path() << '\n';
    }

Possible output:

    The parent path of "/var/tmp/example.txt" is "/var/tmp"
    The parent path of "/" is "/"
    The parent path of "/var/tmp/." is "/var/tmp"
